- Theinvention--described herein may'i'be used by the Government, or any of "its oilicers or employees in prosecution of'work for the Government, orby any other person in the United States, without paymentofany royalty thereona This invention relates. to apparatus for mixing, amalgamatingand grinding-vain sous substances or compounds, either-dry,

' liquid, orsemi-liquid, and has for one offlit's' objects to produce an apparatus whereby the contents of a container maybe thoroughly disintegrated and commingled by rotating the container, the latter being mounted upon rotating rollers.

' contents from side to side while being ro Another object of the invention is to provide a container adapted to rapidly move its Another object of the invention is to pro duce 'a device of this character adapted to support a plurality of independent containers with means for independently rotating them, and so constructed that the containers are" loosely supported and adapted to be re moved one at a time and replaced by other containers.

ith these and other objects in vew the invention consists in certain features of construction as hereinafter shown and described and then specifically pointed out in the claims; and in the drawings illustrative of the preferred embodiment of the invention Fig. 1 is a side elevation,

Fig. 2 is a transverse section on theline 2-2 of Fig. 1. v

The improved apparatus comprises primarily a receptacle for the material or product to be mixed or ground and mounted upon rollers disposed in spaced relation and rotated in the same direction, the receptacle being thus correspondingly rotated and the contents thoroughly mixed and commingled.

The receptacles may be constructed of any suitable material but will preferably be of glass, porcelain lined metal, vitrified Ware,

lead lined, or otherwiseconstructed to; resist the action of acids or the like. For the pur pose of illustration the receptacles, indicated at 10,'are each formed'with a contracted nozzle or mouth 11, having a suitable stopperindicated at 12, but it is not desired to limit the I form of the containers or the material of which they are constructed The rotating rollers may be of any required length andsize be arranged in pairs one above the otherand Supported for rotation "11m Tsuitable' frame-x i work. For the purp'osejof illustration a f" c o11 ven-tional framework' is shown comprising 20-21 as shown; By this means the standcorrespond to the number of be employed. i

The base members 14 are formed with bearings 22 to receive the journals of shafts 23. Attached to the standards 13 are bracket devices 24 each carrying a bearing 25 v to support the journals of shafts 26. I The standards maybe of any required height to carry any required number'of the brackets, but one set of the brackets only are shown for the purpose of illustration.

The shafts 23-26 support roller devices 2.7, preferably of wood, and each provided with a jacket or covering 28 of suitable yielding material. The drums 27 are disposed in eccentric position upon the shafts 23 and 26 so that the containers 10 are thrown from side to side as they are rotated to agitate the contents,,as hereafter more fully explained. The yieldable jackets will preferably be sections of rubberhose stretched over the drums or rollers 27, but may be otherwise constructed, if required,

One of the shafts 23 and one of the shafts 26 are further extended to receive chain wheels 3334 over which an endless chain 35 operates. The shaft 23 which contains the chain wheel 33 is further extended as shown in F ig. 1 to receive the rotating medium, not shown.

It will be obvious by this arrangement that when the last mentioned shaft is rotated by any suitable power the sets of rollers will be simultaneously rotated in the same direction through the action of the chains, and when the receptacles 10 are disposed upon the rollers as shown, the receptacles will be rapidly rotated and cause their contents to bethoroughly mixed, ground,

or commingled,- as; before described, and thrown from. side to side at thesame time by the action o'flthe eccentricallyarranged drums.

The receptacles being disposed]loosely upon the rollers can be removed one at a time and replaced by other receptacles witl1- out. disturbing the remaining receptacles. Thus compounds or, material of various kinds may be. operated upon at the. same time and the contents of the various. reiceptacles separatelyretained; i

"Iheimp'roved device may beemployed for grindingor mixing various substances either I powdered, llQlllCl. or semi-l quid, as, may be concrete, clay and required, and will be found of special advantage ,in grinding or mixing lymph or compounds employed in vaccination or inoculations of various kinds. The device may be arranged for relatively large containers and likewise be employed for mixing like material or com pounds. I

Having thus described the invention what is claimed as new is 1. In an apparatus of the class described, a coactingpair of rollers of unifonndiameter; from end to end and having journals arranged eccentrically thereto and mounted for rotation, and means forv simultaneously actuating said rollers, said rollers being adapted to support and revolve in an oscillatory manner a plurality of.con-

tainers-arranged end toend and independently disposableupon and removable. from said rollers.

- 2.. Inan apparatus of clas s coacting pairs ofrollers of uniform (diameter from end to end and each pair having journals arranged.uniformly ,eccentricallyf thereto. and mounted for rotation, means for 3 simultaneously actuating ,saijdwrollers, and

a{ plural ty, of conta ners arranged enda pon saichrollers and' b'earing loosel" thereon. i
